Question

Please help me I dont know the answer I also dont want to do it

Answer 1

We need first to replace the value of m

`1+(-(2)/(3))-(-(9)/(2))`

and then apply the sign rules

`\begin{gathered} 1+(-(2)/(3))-(-(9)/(2))=1-(2)/(3)+(9)/(2) \\ =(6-4+27)/(6) \\ =(29)/(6) \\ \end{gathered}`

then the answer is 29/6.
